摘要： A method for reducing frequent idle handoffs of a wireless communication device is described. A registration request is received by a base station or a femto access point from the wireless communication device. The number of registration requests received from the wireless communication device are counted while the registration timer is running. It is determined that frequent handoffs are happening when the number of registration requests received is greater than a registration threshold. A transmit power of a femto access point is adjusted if the number of registration requests received indicates that frequent handoffs are happening.

摘要： An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.

摘要： An access point is identified based on a plurality of pilot signatures (pseudo-random noise, PN, spreading codes or scrambling codes). Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature (e.g. PN offset or PN phase). For example, an access point may use one PN offset to generate and transmit a pilot signal and transmit a different message that identifies (includes) at least another PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot- related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal. In a certain aspect of the invention, a femto management system maintains a pool of PN offsets that may be allocated to femtocells mapping between PN offsets and cell -IDs may be carried out.

摘要： An access point is identified based on pilot signal information that appears on different frequencies. Here, a combination of one or more pilot PN spreading codes or one or more PN offsets on different frequencies are used to uniquely identify an access point. For example, upon receipt of a pilot measurement report, a network entity may uniquely identify an access point that transmitted the pilot signals based on at least one pilot PN spreading code or at least one PN offset and a plurality of frequencies identified by the report. Also, to facilitate acquiring this information, a network entity may request an access terminal to conduct an inter-frequency search for pilot signals. Also, an access terminal may maintain pilot information corresponding to access points in a network and use this information to autonomously conduct inter-frequency searches for pilot signals.

摘要： Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a minimum coupling loss from a transmitting node to a receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference. Transmit power may be defined based on channel quality. Transmit power may be defined based on a signal-to-noise ratio at an access terminal. The transmit power of neighboring access nodes also may be controlled by inter-access node signaling.

摘要： Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.

摘要： Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management-related techniques.

摘要： Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.

摘要： In some aspect restricted access nodes are assigned to a designated common channel while access terminals that are in active communication with a macro access node may selectively be assigned to the designated channel. In some aspect an access terminal associated with macro access node may perform a handoff to a different carrier when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspect an access terminal associated with a macro access node may perform a handoff to a different carrier based on location information. In some aspect access to a restricted access node is controlled based on policy and/or based on operation of an access terminal associated with the restricted access node.
